My A/C fan has been acting erratically and yesterday found out my battery is drained. Had to jump it. I know that there are alot of threads regarding FSU but I want to know if there is something I can do to prevent battery drain for temp solution until I get the new FSU. I just unplug the battery after I parked today. Thanks...
